Base image is debian:jessie;
has openjdk-7-jre installed and the pokepon source code in /opt/pokepon.
Runs as user 'pokepon' and exposes 12344.
docker run -d -p 12344:12344 silverweed/pokepon_server:latest
Doesn't have any volumes, but you can save the server database by mounting a volume and instructing the server to use a custom db location:
docker run -d -p 12344:12344 -v /var/log/pokepon silverweed/pokepon_server:latest -d file:///var/log/pokepon/server.db
(if you prefer, you can bind-mount the volume to your host or use a data-only container to keep the server database).
